config: Node count vs Core count

[akutz]

Hi @taylor, et. al,

After a long discussion with some people much smarter than myself (which, sadly, is most people) regarding vCPU counts and cores, we realized we needed your feedback. The current thinking/recommendation is to use no more than 8 vCPUs in a given VM because the smallest NUMA node is 8. Now, while we can still create VMs with 16 vCPUs, I did get to thinking: what if we keep the vCPU count at 8/VM and alter the master/worker node counts from 3/1 to 6/2 (or whatever distribution you think makes sense).

You understand the requirements far better than I do, so I wanted to reach out and see if my suggestion is worth exploring or even supported at all. Thanks!
